How Microbial Fossils Illuminate Life’s Origins
Introduction: A Window into Earth’s Deep Past About 3.5 to 4 billion years ago, Earth was a starkly different place. The atmosphere lacked free oxygen, oceans were acidic and iron-rich, and volcanic activity shaped a volatile landscape. Yet, within this harsh world, microbial life not only persisted but also left behind some of the oldest…
